GONE-LOCK FOR BALL-BEARINGS.

SPECIFICATION forming part of Letters Patent No. 630,915, dated August 15, 1899.

Application iiled May ll, 1899. Serial No. 716,462. (No model.)

To @ZZ 'll/'7mm t may concern.'

Be it known that I, FREDERICK MYERS, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Cone-Locks for Ball-Bearings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to cone-locks for ballbearings for use on railway rolling-stock, bicycles, or other vehicles; and the object sought to be accomplished is to produce a device of this character which shall be simple in construction, reliable and eiiicient in use,

and which will be easy to operate. I attain this object by means of the construction shown in the accompanying drawings, which form a part of this specification, and in which- Figure l is an end view of a bicycle-hub, showing my invention applied thereto. Fig. 2 is a partial vertical section of the end of the hub. Fig. 3 is a plan View of my cone lock or disk. Fig. 4c is an end view of a bicyclehub, showing one modification of my invention; and Fig. 5 is a similar view of another modification of the same.

Like numerals of reference designate like parts wherever they occur in the various views of the drawings.

l is a bicycle-hub of ordinary construction and provided with the usual interior screwthreads 2 for the adjustment of the ball-cone.

3 is my cone, which is provided with exterior screw-threads to fit the interior portion of the hub, and this cone has a smooth outer surface and a central screw-threaded aperture 4, which conforms to the exteriorlythreaded spindle 5. Secured to the outer face of the cone 3 is a detent or pawl 6, which is pivoted upon the pin or stud 7. This pawl is held sufliciently tight against the face of the cone by the pin 7 to prevent its movement by the ordinary jarring of the wheel.

8 is my cone-lock, which consists of a disk of metal having notches 9 extending entirely around the periphery thereof. This lock or disk is provided with a central aperture 10, designed to fit the spindle 5. A lip or projection ll is formed at some point within the aperture l0, and the spindle 5 is provided with alongitudinal groove 12, which conforms to the shape of the lip 11, and when thelocking-disk is placed upon the spindle 5 it is prevented from revolving or turning thereon by said lip and groove. The balls 13 are seated in the bearing in the usual or any well-known way, it being immaterial to my invention what form of ball-bearing may be used. Vhen the cone 3 has been adjusted to the desired position within the hub, the pawl 6 having been raised out of contact with the locking-disk 8 for such purpose, said pawl is then moved upon its pivot 7 until its toe is inserted into any one of the notches 9 in the locking-disk 8.

It will be understood, of course, that there is a nut lat upon the end of the spindle 5, which holds the parts in contact, as is usual.

Instead of the pawl 6 I may use a hinged toe 6X, as is shown in Fig. et, or a sliding bolt 7X, as is shown in Fig. 5.

It will be obvious from the foregoing that my device is extremely simple and permits of ready adjustment of the cone and requires but a moment to lock) the same in adjusted position. At the same time the locking device is entirely out of the way and cannot become disordered and inoperative.

I am aware that manychanges maybe made in the details of construction of my device without departing from the spirit and scope of my invention. Therefore I do not wish to be limited to the exact construction shown.

lVh'at I desire to secure by Letters Patent and claim is A cone-lock comprising a disk having notches in its periphery, a central recess and a lip projecting into the same, in combination with a grooved spindle, a ball-cone, and a detent secured to the outer face of said cone, said detent adapted to be moved into position to engage with any of the notches of the disk and to be disengaged therefrom, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

FREDERICK MYERS.
